McDonald’s Free WiFi: Turning SSIDs into Ads

In Spain, McDonald’s offers free WiFi to all its customers. Since the WiFi signal reaches quite far, customers in surrounding restaurants also tend to use the McDonald’s network.

So McDonald’s decided to attract new customers via their own WiFi network. They simply changed the signal’s name into a message and embedded a promotion into it. 🙂

The simplest media channel you already own

This is a tiny idea with a very clear mechanism. A WiFi network name is a broadcast surface. It shows up exactly when people are deciding where to sit, what to order, or whether to move.

Instead of treating WiFi as utility, McDonald’s treated it as a micro-channel for demand capture.

Why the WiFi name works as advertising

  • High intent moment. People looking for WiFi are already in “connect me now” mode.
  • Local reach. The signal spills into nearby venues, where potential switchers sit.
  • Zero-click visibility. You see the message before you even connect.
  • Low cost, repeatable. Updating an SSID is simple, fast, and scalable.

Where this crosses from clever to strategic

The strategic move is not the pun. It is the use of owned infrastructure as a distribution channel. When your message sits inside a system people actively scan for, you reduce friction and increase the odds of action.

It is also a reminder that not all “digital” has to be an app. Sometimes it is just naming.

What to take from this if you run retail or CX

  1. Audit your hidden touchpoints. SSIDs, receipts, kiosks, queue screens, packaging, all are media surfaces.
  2. Message at the decision point. Proximity channels work best when they align with immediate behavior.
  3. Keep the offer instantly understandable. People scan lists quickly. Clarity beats cleverness.
  4. Test and rotate. Like any channel, vary the message to learn what actually moves footfall.

A few fast answers before you act

What did McDonald’s do with its free WiFi in Spain?

It changed the WiFi network name into a message and embedded a promotional offer into the SSID to attract people nearby who could see the network on their devices.

Why does the WiFi signal matter here?

Because it reaches beyond the restaurant itself, meaning people in surrounding venues can still see and use the network, making it a local acquisition channel.

What is an SSID in this context?

It is the WiFi network name that appears in a device’s list of available networks. Changing it changes what people see before connecting.

Is this a “growth hack” or a real marketing tactic?

It is both. It is a lightweight tactic, but it is grounded in a real channel. Owned infrastructure that reaches potential customers at a high-intent moment.

What is the transferable lesson for brands?

Look for owned, ambient digital surfaces where people already scan for utility, then place a clear message there that can drive immediate action.

HERE balloons

Seoul has the highest gasoline consumption in the world. With parking space scarce, people in Seoul drive around 15km a month to find space for their cars. This is equivalent to 1 Litre of gasoline being used only for parking.

So to help save gasoline, South Korean oil brand, S-Oil teamed up with Cheil Worldwide to devise a new way of telling people that there was a parking space available right next to them. Bright yellow HERE balloons were setup for each parking space. Then as a car parked, the balloon would fall. On leaving the space the balloon would rise again. Hence drivers around could see the colourful balloons from far away and spot the empty spaces without wandering all over.

In just one day, 700 cars used 23 litres less oil. Over a whole year, they saved much more.

Heineken Departure Roulette

Board at JFK Terminal 8. A single red button. A real decision. To embody Heineken’s adventurous spirit, Wieden + Kennedy in New York sets up a Departure Roulette board at JFK’s Terminal 8 and dares travelers to play. If they press the button, they drop their existing plans and go somewhere totally new and exotic.

The commitment is real. The travelers who take the dare receive $2,000 to cover expenses and get booked into a hotel for two nights at the new destination. This is the recently released video of how it unfolds at JFK.

The stunt links to a broader idea. The game draws inspiration from Dropped, a Heineken campaign launched from W+K Amsterdam in which four men get sent to remote destinations, and the adventure of getting back gets filmed.

Why this stunt works

It makes spontaneity measurable

Most people can say they are spontaneous. Departure Roulette forces a binary choice in public. Press or walk away. The brand promise becomes an observable action.

It raises stakes without needing complex rules

The mechanic is simple. The tension is high. You do not need a long explanation to understand what is at risk: your plan.

It turns a brand value into a story people retell

The red button is a prop with meaning. It compresses the entire narrative into one symbol that is easy to remember, share, and debate.

How to apply the pattern

  1. Create one unmistakable action. A single step that proves intent, not interest.
  2. Make the trade-off clear. People must know exactly what they give up and what they gain.
  3. Design for the decision moment. The most valuable content is the second before and after commitment.
  4. Operationalize the reward. If logistics fail, the story turns from daring to disappointing.

What to measure beyond views

  • Participation rate. How many approached travelers agree to play.
  • Completion rate. How many press the button after hearing the rules.
  • Story lift. How often people retell the mechanic correctly.
  • Brand linkage. Whether the audience connects the act to “adventurous spirit,” not just “free trip.”

A few fast answers before you act

What is Departure Roulette?

A physical airport activation where travelers can press a red button and immediately swap their planned trip for a surprise destination.

What is the core mechanic?

One irreversible choice that turns a brand value into an action people can witness.

What makes it repeatable for other brands?

The format is not travel. It is a high-stakes choice with a simple trigger, a clear trade-off, and a real reward.

What is the biggest failure mode?

When the commitment is not credible, or the operations cannot deliver the promise.
